Amount that Gabriel earns if he sells 35 jackets
= 35 x 15
= $525
Big difference between the amount on the jackets and the sweaters
= 525 - 400
= $125
Small difference the amount on one jacket and the sweater
= 15 - 10
= $5
Number of sweaters that Gabriel sold in December
= 125 ÷ 5
= 25
Number of jackets that Gabriel sold in December
= 35 - 25
= 10
Answer(s): 10
